Recently, when checking on-chain data, I often encounter those moments of "lag": the page spins in circles, balances are a half-second behind, and the history suddenly goes blank for a second. To be honest, it's not that the chain really stopped; it's the intermediate data services catching their breath—indexers need to organize a bunch of events into easily queryable tables, and Subgraph (similar to custom indexing rules) needs to sync, sometimes falling behind when blocks come in quickly; plus, with RPC rate limiting, during airdrop season, everyone is frantically clicking tasks, platforms are implementing anti-witchcraft measures and even points systems, and token farmers are working as hard as in an office job, causing the public nodes to get overwhelmed with calls. Now I tend to open multiple data entry points for comparison; don’t panic just because you see "0"—just wait for it to catch up first.
